1933 F/R/W Coaxial DFB Laser Diode 1310 nm, Wide Bandwidth 5 MHz – 4000 MHz DATASHEET | AUGUST 2012 FIBER OPTICS EMCORE’s Model 1933 DFB lasers offer a low cost solution for linear fiber optic links. These components can be cooled with external thermo-electric coolers for high stability, or run without TEC’s to reduce power consumption. The DFB laser builds upon Ortel’s long history of high performance, leading edge designs in CATV, wireless, and high speed digital applications. The laser diode devices are packaged in a compact hermetic assembly together with monitor photodiode and isolator, for flexible integration into various transmitter configurations.
